GEOTECHNICAL ENGINEERING – I

 

Historical development of Soil Engineering – Origin and general types of soils – soil structure,

clay minerals-Three phase system- Identification and Classification of soils
Soil water – capillary phenomena – concept of effective and neutral stresses – Permeability
– determination of coefficient of permeability in the laboratory – Seepage flow – Head,
gradient, pressure – steady state flow – two dimensional – flow net.
Vertical stress distribution in soil – Boussinesq and Westergaard’s equation –
Newmark’s influence chart – principle, construction and use – Equivalent point load and
other approximate methods – pressure bulb. Compaction
Shear strength – Mohr-Coulomb failure criterion – shear strength tests – Different
drainage conditions – Shear properties of cohesionless and cohesive soils – Use of Mohr’s
circle – relationship between principal stresses and shear parameters.
Compressibility and consolidation – Terzaghi’s one dimensional consolidation theory –
pressure void ratio relationship – preconsolidation pressure – Total settlement and time
rate of settlement – coefficient of consolidation – curve fitting methods – Correction for
construction time.
